ELECTRIC IGNITING SPECIFICATION forming part of Letters Application iled October 11, 1888.

To aZZ whom it may concern:

Be it known that we, MANUEL CARRANZA, of Guatemala, Republic of Guatemala, Central America, and Jos MARIA TINooo, of

the city and county of San Francisco, State of California, have invented an Improvement in Electric Igniting Devices for Lamps; and we hereby declare the following to be a full,

clear, and exact description of the same.

Our invention relates to electric igniting devices for lamps; and our invention consists of the constructions and combinations of devices which we shall hereinafter fully describe and claim.

Referring to the accompanying drawings for a more complete explanation of our invention, Figure l is a vertical section of a lamp,

showing our improvements applied thereto. Fig. 2 is a perspective View of the lighting- 2o frame.

A is the reservoir of the lamp, which may be circular or other shape.

B is the fomit of the lamp, supported from the reservoir by the standard C. Within the reservoir is a closely-fitting piston a, above which is seated a spiral spring a', serving to press the piston down. The piston is also provided with a number of downwardly- Opening valves CL2. A rod in the shape of a rack-bar a3 extends upwardly from the piston through the top of the reservoir and is engaged by a pinion c, mounted on a crossshaft c', journ aled in the standard C, said shaft having on its other end a suitable thumbscrew, whereby it can be rotated, so as to raise the piston a.

D is the supplyor feed pipe extending from near the bottom of the reservoir to near the top of the fount,

D' is a safety or overflow pipe extending from near the top of the fount downwardly into the top of the reservoir above the piston.

The operation of the parts as far as described is as follows: Oil is fed to the reservoir through the hoppers or funnels a4 on its top. By Ineans of the pinion and rack the DEVICE FOR LAMPS.

Patent No. 412,464, dated October 8, 1889.

Serial No. 287,862. (No modem above it passes down through the valves cu2 into the reservoir under the piston. The 5o spring a', acting on the piston, serves to force it downwardly against the oil, thereby pressing the oil upwardly in the feed-tube D into the fount above. I'Vithin the fount is a float E on the end of a pivoted lever c, the other end of which carries a valve e, which is seated in and adapted to close the upper end of the supply pipe or tube D. Therefore, when the oil reaches a certain level in the fount it raises the float and causes the valve E to shut o 6o the supply; but when the oil in the fount has been consumed sufficiently to lower its level the iioat drops and opens the feed-tube. In case this mechanism should fail to operate, the safety-pipe D', serving as an overliow- 65 tube, prevents an undue level of the oil in the fount and a possible overliow through the wick-tube. Traversing the supply-tube is a cut-oif valve d, operated by a bar from the outside. This valve may be operated when 7o it is desired to cut off the supply of oil from the reservoir and to only consume whatever oil is in the fount. In the safety-tube D about at a level with thc bottom of the fount, is an opening d', which is controlled by a valve d, 7 5 operated from without, so that if it be desired to let the oil out at once which is within the fount the opening may be uncovered, thereby allowing the oil to run down the pipe into the reservoir.

F is the burner inclosing the wick-tube f, in which is the'wick f.

G is an extinguisher-plate, which has the shape of an elbowor bell-crank lever, pivoted at its angle at the point g. The upper end g of the lever is curved and is adapted to be thrown directly over the top of the wick, thereby extinguishing it. It is held back, however, in its normal position by means of a small spring g2. This extinguisher-plate is 9o operated by means of a lever II, which is pivoted at 7L to a standard on the top of the fount. One end of the lever is forked and embraces a fixed pin g3 on the horizontal arm of the extinguisher-plate,while the other end of the piston o is raised, so that the oil which is lever has an upwardly-extending button h.

The spring g2, holding the. extinguishingplate back outof action, also causes the button to'remain up. Therefore by pressing down on the button the lever H is vibrated, so as to turn the extinguishing-plate on its pivotal center and throw its upper curved end over the wick, thereby extinguishing the light. On the other side of the wick-tube is atransverse shaft I, which is mounted and adapted to rock in electrically-insulated bearings i by means of a pivoted lever J, the forked inner end of which embraces a bail j on the shaft. The outer end of the lever has a button j', whereby said lever is operated.

Firmly secured to the shaft I are arms K, extending upwardly at each end ofthe wicktube. In the top of these arms are -fitted opposingl set-'screws L, extending between the ends of which is a spiral wire M, made of platinum plated with iridium. It will be seen, therefore, that by pressing down the button j the lever J will rock the shaft I and its upright arms K, thereby throwing `the platinum wire into contact with the top of the wick. A spring S serves te return the parts to position and hold the wire away from the wick.

The platinum wire is included in an elect-ric circuit as follows: Under the reservoir A is a hollow base N, in which is included or contained a suitable electric pile or battery,.

from which extend the circuit-wires w, which are preferably carried upwardly within the walls of the lamp-structure. At one end of the shaft I, and in contact therewith, is a metallic piece O, with which one of the wires zu connects. At the other end is a bent metallic piece O', the end of which lies justl back of one of the upright arms K of the shaft, though when said arm is pressed backwardly in normal position it is not in contact with the metallic piece, but only comes in contact with it when the arm is thrown kforward. With this metallic piece O the other wire [w is connected. y

The shaft I is in two sections, as shown, connected at the center by an insulator or non-conducting-piece i', so that the course of the Vcurrent must be through the platinum wire. The circuit, however,- remains open when the parts are in normal position, for there is then no contact between the piece O and the arm; but when the button is pressed down, so as to swing the parts over and carry the platinum wire directly over the top of the wick, then at that moment the circuit is closed by the contact of the arm with the piece O', so that the current passing through the platinum wire heats it to incandescence, and said wire being in contact with the top of the wick lights it. When the button is released, the parts resume their normal positions and the circuit is opened.

In order to adjust the platinum wire accurately to the height of the wick, we make the arms K extensible by securing to their tops, by means of elongated slots and set-screws k, the pieces 7c', which carry the set-screws L and wirev M. The set-screws L serve to keep the platinum wire taut.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a lamp, a lighter for the wick, consisting of a swinging frame adapted to be moved forward and backward to close and open an electric circuit, said frame having a spiral platinum wire in said circuit, whereby it is heated to incandescence, the said wire being in contact with the top of the wick, substantially as herein described.

2. In a lamp, a rocking or swinging frame in an electric circuit and adapted to be moved forward and backward to close and open said circuit, a wire carried by said frame and adapted by the movement of the frame to be wires and the swinging frame, whereby the circuit is alternately closed and opened by the swinging of said frame, substantially as and for the purpose herein described.

4. In a lamp, the rock-shaft I andthe lever-connections and button by which it is operated, in combination with the arms of the rock-shaft, the wire M, secured between the tops of the arms and adapted to be thrown into contact with the top of the wick by the movement of the shaft, and an electric circuit, including the wire, whereby it is heated to incandescence and lights the wick, substantially as herein described.
